Blueberry fruit drop-associated virus: A New Member of the Family Caulimoviridae Isolated From Blueberry Exhibiting Fruit-Drop Symptoms

A Virus Associated with Blueberry Fruit Drop Disease

During the past few years a fruit drop symptom has been observed in several blueberry fields in Oregon, Washington and B.C. The plants flower normally, though the young leaves and flowers have a transient red coloration that is absent in healthy plants. The fruit develops to 3-5 mm in diameter and then aborts so that affected bushes mature virtually no fruit. The incidence within fields increas...

Blueberry and cranberry fruit composition during development1

Compositional changes that occur during fruit development affect both the organoleptic and nutritional quality of small fruit. Compositional changes in blueberry (Vaccinium corymbosum L) and cranberry (Vaccinium macrocarpon Aiton) fruit were determined at 3 maturities (white, turning and fully colored) during 2 seasons by analyzing sugar, acid, total phenolic, and total anthocyanin composition,...

Blueberry fruit response to postharvest application of ultraviolet radiation

Blueberries (Vaccinium corymbosum, cvs. Collins, Bluecrop) were exposed to ultraviolet light-C (UV-C) radiation treatments from 0 to 4 kJ/m2 rior to 7 days storage at 5 ◦C plus 2 days at 20 ◦C, 90% RH. Weight loss and firmness were not affected by light treatment. Decay incidence from ipe rot (Colletotrichum acutatum, syn. C. gloeosporioides) on fruit was decreased by 10% with 1–4 kJ/m2 UV-C li...

Factors Affecting Fruit Set/Early Fruit Drop in Avocado

Pruning severity affects yield, fruit load and fruit and leaf traits of ‘Brigitta’ blueberry

Pruning is crucial to balance productivity and fruit quality in blueberry orchards. Slight, conventional and severe pruning treatments were applied on 4and 5-year old bluberry plants cultivar ‘Brigitta’ to evaluate their effect on yield, leaf area, gas exchange and fruit load as driver of fruit quality traits. Yield and berries per plant decreased with increasing pruning severity, whereas canop...
